Emissions and immissions measurement

Emissions and immissions measurement

Since 1991, the Laboratory of Emission and Immission Measurements of ELVAC EKOTECHNIKA s.r.o. has been authorized for one-off measurements of pollutant emissions for the widest range of pollutants, including technological measurements. We carry out emission measurements of all industrial sources of air pollution according to customer requirements. Since 2008, the Laboratory of Emission and Immission Measurements of ELVAC EKOTECHNIKA s.r.o. has been accredited for emission measurements according to ČSN EN ISO/IEC 17 025.

The Laboratory of Emission Measurement and Immissions has continuous analyzers of gaseous pollutants (TOC, CO, SO2, NOx, N2O) and manual sampling equipment for emission measurements. It uses automated gravimetric apparatus for isokinetic sampling.

In addition to authorized emission and immission measurements, the laboratory performs various types of technological measurements, work environment measurements and consulting activities.

We are a member of the Association of Authorised Laboratories for Emission Measurement ALME and regularly participate in inter-laboratory comparison tests.

The laboratory undertakes to maintain the confidentiality of all information obtained or created during the performance of laboratory activities.

ACCREDITATION

Since 2008, our Laboratory for Authorized Measurement of Emissions and Immissions has held an ACCREDITATION CERTIFICATE issued by the Czech Accreditation Institute, o.p.s. (national accreditation body).

Methods for determining pollutants

measurement of emissions - particulate matter - gravimetric determination

emission measurement - sulphur dioxide - spectrometric determination

emission measurement - carbon monoxide - determination by spectrometric and electrochemical cell

measurement of emissions - nitrogen oxides - spectrometric, chemiluminescence and electrochemical determination

measurement of emissions - organic substances expressed as total organic carbon (TOC) - flame ionisation method

measurement of emissions - chlorine and its gaseous inorganic compounds - determination by volumetric, photometric and ion chromatography

Frequently Asked Questions (FAQ)

Edit Content

Authorized emission measurement is an official, government-recognized one-time measurement of pollutant concentrations in exhaust gases/compressed air, performed according to reference methods by an accredited/authorized laboratory. It serves to demonstrate compliance with emission limits and legal obligations. We have been a laboratory authorized by the Ministry of the Environment since 1991 and accredited according to ČSN EN ISO/IEC 17025 since 2008. We have continuous analyzers (TOC, CO, SO₂, NOₓ, N₂O) and equipment for manual and isokinetic sampling.

Edit Content

Technological measurements are purposeful and tailored to your technology – they are used when commissioning equipment, optimizing, troubleshooting, or verifying efficiency. These are not one-time authorized measurements required by law, but practical measurements for operational decisions. We also perform these measurements and will suggest a suitable scope and methods for you.

Edit Content

We measure virtually all industrial sources: heating plants and power plants, chemical plants, cement plants, waste incinerators, asphalt plants and concrete plants, biostations and solid fuel boiler rooms, refineries, paper mills, and metalworking operations (foundries, rolling mills).

Edit Content

When you need to prove compliance with legislative requirements and emission limits set by the Air Protection Act and your operating permit. We will help you set the correct scope and timing of measurements to meet the requirements of the authorities.

Edit Content

The frequency is determined by legislation and the conditions of your permit (IPPC/ZOZ). Upon request, we will propose a schedule in accordance with the obligations of the specific source. (General intervals vary between sources.)

Edit Content

Depending on the required substances, we use continuous gas analyzers and perform manual sampling; for dust/TZL, we use isokinetic gravimetric apparatus. Sampling and analysis are performed according to reference methods (e.g., chemiluminescence, flame ionization detection, ion chromatography, AAS/ICP, etc.). The output is a report with results and evaluation against limits.

Edit Content

Ensure safe access to consumption points (platform/ladder), operational condition of the source in accordance with the permit, documentation on the process (fuel, output, operating parameters), connection to the electrical network for the equipment, and contact details for the responsible person.

Edit Content

Approximately 6 hours per source as standard; up to around 12 hours for more extensive measurements or multiple monitored parameters. Processing the report usually takes another 1–2 working days.

Edit Content

We usually prepare the measurement report within 1–2 business days after completing the work on site. The operator is responsible for submitting the report to the Czech Environmental Inspection Agency (ČIŽP); upon request, we can prepare all the necessary documents and advise you on how to submit them.

Edit Content

The price is individual—it depends on the number and type of substances measured, the scope of the campaign, the accessibility of the measurement sites, and logistics. We will provide a quick calculation after a short consultation (ekotechnika@elvac.eu, +420 724 844 378).

Edit Content

The amount of penalties is determined by the relevant authorities in accordance with the Air Protection Act and the conditions of the permit. If we find any non-compliance, we will propose corrective measures and appropriate technologies to reduce emissions; we can also verify their effectiveness through measurements. (We describe our general approach in our services.)

Edit Content

Authorized emission measurements may only be performed by a laboratory authorized by the Ministry of the Environment or accredited for the given methods and substances. ELVAC EKOTECHNIKA has all the necessary authorizations and certificates.

Edit Content

Yes. We perform authorized and technological measurements throughout the Czech Republic and are able to meet the requirements of EU member states.
